A Method for Removing the Impulse in Image Processing
Lijie Zhang, Haili Yin · 2009
By investigating into the directional derivatives, a method used to remove the salt and pepper noise in image processing is proposed in this paper. Numerical experiments prove that this method can filt the impulse noise from the noised images efficiently. Furthermore, comparing with the median filter, it also does well in keeping the outline and details of processed images.
